  1. Re: slow video

    Man,

    I can suggest you something that you can try with 24 bit colors.
    You can make these specific modifications in your /etc/X11/XF86Config
    file.
    Open it in any editor as root and follow these steps:

    1. Change the driver from "nv" to "nvidia" in Device section.

    2.In the Module section, make sure you have:
    Load "glx"

    3.You should also remove the following lines:
    Load "dri"
    Load "GLcore"

    4. Add these lines in Device section:
    VideoRam "WHATEVER IS YOUR CARDS VRAM IN KB"
    Option "NvAGP" "3"
    Option "NoLogo" "yes"
    Option "RenderAccel" "yes"
    Option "DigitalVibrance" "128"

    5. Change the "depth" to 24 in Screen Section.

    6. Also make sure that you enable swap.
    You can check if it is running properly by issuing the command:--
    swapon -s
    If it gives you the priority as -1 and used as 0. it sure isn't
    working.
    Change the priority to the max "32767" by changing the option
    Defaults in etc/fstab to
    "pri=32767" without qoutes in swap partition section. Its only going to
    help.

    7. Restart in runlevel 5 and then try to use the glxgears.

    I believe its gonna rock.........
    If it doesn't post it back and i will get to it again.

    Best of Luck.

    Already done.

    Was.

    Commented out.

    > Load "GLcore"


    Wasn't there.

    I'd get that info from XFree86 anyhow. Since it autodetects the amount (in
    this case "(--) NVIDIA(0): VideoRAM: 16384 kBytes"), isn't it rather
    pointless to list it?

    > Option "NvAGP" "3"


    What does that do?

    > Option "NoLogo" "yes"


    Good idea. I KNOW it's an Nvidia chip. I don't have to be told every time.

    Was.

    Turned on, but I don't use much of it:

    total used free shared buffers cached
    Mem: 775172 329596 445576 0 30068 186700
    -/+ buffers/cache: 112828 662344
    Swap: 401616 40496 361120

    Well, I've seen swap not get used, in a machine with enough RAM.

    Filename Type Size Used Priority
    /dev/hda2 partition 401616 40496 -1

    Does the priority matter when there's only one swap partition/file?

    Woohoo, xdm works!

    5166 frames in 5.0 seconds = 1033.200 FPS
    5690 frames in 5.0 seconds = 1138.000 FPS
    5695 frames in 5.0 seconds = 1139.000 FPS
    5692 frames in 5.0 seconds = 1138.400 FPS
    5695 frames in 5.0 seconds = 1139.000 FPS

    Not too shabby...

    Now I don't know why it would care, but Opera segfaults when I'm in runlevel
    5. When I log in in text mode and then run "startx", it works. Got me.

    I was wrong -- that was in 16bpp. In 24bpp it's about half as fast:

    2156 frames in 5.0 seconds = 431.200 FPS
    2737 frames in 5.0 seconds = 547.400 FPS
    2780 frames in 5.0 seconds = 556.000 FPS
    2779 frames in 5.0 seconds = 555.800 FPS
    2770 frames in 5.0 seconds = 554.000 FPS

    For that kind of difference, 16bpp looks better...
